llhis in scrubbi n 5;",

wheat end ven'l ion relates to machines for brushing, cleaning or scouring other groin oil the type llr which a helix or spiral i s rotated in the groin and exerts the desired action thereon.

so ch helix-z bristles 'lih peripheral llerctoilore or spiral has been provided with ereon pointing radially from itr-i edge or axially from positions 2rdpicent the periphery.

The object of the presentinvention is to provide for a .l'llUlG upon the cl'l'icicnliclcuniozr action ruin.

'llhe in vention consists in making the helix 0 r 1-; pirul o r portion of some, ol :1 seuin or dished form or section, 'lhot is with o portion zul iocent to r-iuid, dished the periphery set utzin angle, the portion being; formed. or provided with on obrusive or roughened or brush-like nonsitruelw tion.

it do not limit myself to any particular: angle oi? the dished peripheral part of the spiral, with relation to the remainder, neither do l limit u'iyselif' to any puii'ticulor material or arranger:ientof such dished port to produce the requisite abrasive action.
